A few basic things:

 (1) When downloading using USB, check the "create libdivecomputer
dumpfile" option - that will mean that no actual dives get downloaded,
but you should get a memory dump that you can send to Jef:

    Jef Driesen  <jef at libdivecomputer.org>

 (2) Also send Jef the screenshot from the Cressi App of the profile
and other information from the download, so that Jef sees what it
*should* look like.

 (3) Finally, can you use the "nRF Connect" app to look at the
bluetooth details of that bluetooth dongle thing? I'm assuming you're
using that HAL 9000 BT interface to download on the Cressi app? No
promises, but if it looks like most other serial to BLE dongles, the
BLE side might not be too painful to add.

But there's clearly something wrong with parsing, and that's the
primary issue - downloading over bluetooth won't fix that.
